; Running as root
# id
uid=0(root) gid=1(other)

; All users can read
# ls -l /opt/MailScanner/var/MailScanner.pid
-rw-r--r-- root root 6 Feb 22 08:57 /opt/MailScanner/var/MailScanner.pid

; Testing from prompt as root
# cat /opt/MailScanner/var/MailScanner.pid
13896

# kill -HUP 13896

;  no reload and no output in logfiles :-(

MailScanner is running as root and I think root is allowed to "kill -
HUP" all processes (running Solaris 9 btw, no SELinux involved...)

; Script looks ok and as you see above I can't kill -HUP from
; command line either

# head -1 /etc/init.d/mailscanner
#!/sbin/sh

# ls -l /sbin/sh 
-r-xr-xr-x root root 299496 Apr 7 2002 /sbin/sh

I'm also "out of ideas". This is not a showstopper as I can restart MS,
but I find it strange...
